I don't have the information in front of me (and Miss Jasmine us sleeping on my lap right now - can'y upset the princess ) but I believe cats can die from a raw meat diet. Raw meat lacks an amino acid (lycine I think) which can kill them.

I don't know how ferals survive on raw meat diets??? Other PTers may be able to elaborate.

I feed mine a varied diet of raw, dried and canned food (and BBQ chicken for treats!)
